Empower Technologies(http://www.empower-technologies.com/) offers a Linux port for the Palm III and Palm V series.
The Linux/Microcontroller - uClinux(http://www.uclinux.org) project is a port of Linux to systems without a Memory Management Unit (MMU). Pronounced "you-see-linux", the name uClinux comes from combining the greek letter "mu" and the english capital "C". "Mu" stands for "micro", and the "C" is for "controller". uClinux first ported to the Motorola MC68328: DragonBall Integrated Microprocessor. The first target system to successfully boot is the 3Com PalmPilot using a TRG SuperPilot Board with a custom boot-loader created specifically for our Linux/PalmPilot port.
The pilot-link(http://www.pilot-link.org/) suite of tools contains a robust library and a series of conduits for moving information between your desktop or workstation and your Palm handheld device, such as those made by Palm, Sony, Handspring, Handera, and others. It also includes language bindings for languages such as Perl, Python, and Java. Completely new USB device support for Palm, Handspring, and Sony USB-based PalmOS devices. The conduits read-palmpix (a Kodak PalmPix conduit to convert PalmPix camera images to PNG files) and read-notepad (a NotePad conduit to convert Palm NotePad records to image files) have been added. There is a new pilot-datebook replacement pi-getromtoken (a GetROMToken conduit), full support for passworded OS4 and later devices, a full regression test suite, extensive debug logging.
Pilot-QOF(http://pilot-qof.sourceforge.net/) is an application interface between pilot-link and QOF (Query Object Framework). It supports writing Palm data to QSF XML offline storage and running SQL-type queries on the live data or XML file. QSF XML can be imported into other QOF applications.

SiteScooper(http://jmason.org/software/sitescooper/) automatically retrieves the stories from several news websites, trims off extraneous HTML, and converts them into iSilo or Palm DOC format for later reading on-the-move. It maintains a cache, and will avoid stories you've already read. It can handle 1-page sites, 1-page with diffing, 2- and 3-level sites as well as My-Netscape-style RSS sites. It's also very easy to add a new site to its list. Even if you don't have a PalmPilot, it's still handy for simple website-to-text conversion. Site files are included for many popular news sites including Slashdot, LWN, Freshmeat and Linux Today

Pyrite Publisher enables you to convert content into formats suitable for use on a Palm Computing Platform handheld. It is primarily intended to convert text and web pages into e-books usable with several popular readers, but it has recently begun to support other types of data. Pyrite Publisher currently runs on Linux (and other forms of Unix) and Windows.
Pyrite Template is a (theoretically) general-purpose template processing framework intended mainly for the generation of web pages. Templates use embedded Python code, and processing objects are included to apply them to groups of files, collect data from files into template-accessible variables, generate thumbnails for image collections, and other similar tasks.
Formerly a part of Pyrite, libpisock is a Python binding to the most important parts of the pisock (pilot-link) library that is used by most Unix-based Palm Computing Platform desktop software. It has recently been submitted for inclusion into the main pilot-link distribution; the version here is likely to be either older or newer than the one there.

It creates a new ical calendar file which replaces both the current and archived ones and updates the Pilot DateBookDB to coincide with them. Also included are patches to ical which create a menu item to sync with a Pilot.
P*Wcal(http://www.neosystem.com/wcal) is a process that allows you to synchronize the datebook and todos of Palm Pilot with Wcal. It has multiple Palm synchronization, user authentication to avoid illegal access to the calendars, the ability to synchronize events and todos, the ability to archive Palm events in Wcal, Network HotSync\256 support, quick sync report in the HotSync\256 journal of the Palm, and a complete sync report in Wcal.

The Doc format(http://www.pyrite.org/doc_format.html) is the de facto standard for large text documents on the Palm Computing Platform. It enjoys wide support in both software and content, but documentation is sparse. This document is an attempt to describe the Doc format for the edification of programmers who are interested in writing Doc-compatible software, and to encourage programmers not to break the format in incompatible ways. This document is totally unofficial, and derived from examination of existing Doc files and applications.
CSpotRun(http://www.32768.com/bill/palmos/cspotrun/) is a reader for documents in the Pilot DOC format. It's targeted at those who do not use a reader enough to justify spending the money on one, and was designed to be smaller and simpler than the commercial readers. It's available for download in English, French, German, Portuguese, or Spanish.
Doc Toolkit(http://purl.oclc.org/net/n9mtb/cq/dtk/) is a set of tools for building e-texts in the "Doc" format which is the de facto standard for large texts on the Palm Computing platform.

the pilot-link package.
This version can also read/write the address database direct from/to the Palm Pilot.
The program can also be used as a general address manager without a 3Com Palm Pilot. Some of the record fields may not
be very meaningful in this case.

prc-eclipse(http://www.redfelineninja.dsl.pipex.com/software.html) is an Eclipse plugin that provides support for the GNU-based PalmOS development tools, prc-tools. It provides two useful features: The first is to allow the use of the Eclipse graphical debugger interface instead of the textual gdb interface. The second is (searchable) access to PalmSource's extensive online help through Eclipse's built-in help system. These combine with the C/C++ Development Tools to make a powerful development environment.
Toucan(http://toucan.sourceforge.net/) is based on Tcl/Tk (of course!) and provides an environment for developing Palm Tcl applications using Tk widgets to give an approximate appearance to the Palm Forms interface. It is not a 100% perfect look-and-feel (at least with the initial version), but it is sufficient for the user to design the Forms interface and create the Tcl scripts to glue them all together.
From newsgroup.pilot.programmer.gcc GNU Pilot SDK FAQ
Palmdoc(http://www.netmeister.org/apps/palmdoc/) , inspired by javadoc, is a Perl program intended to help Palm programmers document their projects. It takes a projectname as input and walks along the project files, generating an HTML document from the code and the comments. While palmdoc has some strict rules, it helps the programmer maintain a clear document-st ructure and minimizes the effort of having to write seperate documentation for each project.

WabaJump(http://www.wabajump.org/) is an API which allows applications written for Waba to be compiled to a PalmOS executable via Jump. This removes the application's dependence on the WabaVM, so that only one file needs to be installed on the user's device, instead of four. This also speeds up the application, because it's now a native application instead of an interpreted application.
